Abstract

Une seringue de sécurité comprend un cylindre creux, un plongeur avec un piston, un adaptateur en caoutchouc dur et une aiguille. Le piston comprend un élément en caoutchouc ayant un espace central pour permettre à la pointe du plongeur de se déplacer axialement dans celui-ci, pour effectuer des fonctions pour permettre respectivement une extraction de liquide commençant au niveau Occ et un verrouillage réciproque. L'adaptateur fixé à un nez en saillie distal du cylindre et de l'aiguille est verrouillé à une partie filetée dans l'adaptateur par ajustement, lequel comprend une structure de verrouillage réciproque femelle à l'extrémité proximale pour recevoir une structure de verrouillage réciproque mâle, alignant des moyens de détente du plongeur, caractérisé par le fait que la structure de verrouillage réciproque mâle est détendue en restant à l'intérieur, portant l'adaptateur avec l'aiguille dans le cylindre lors de la rétraction du plongeur, de telle sorte que l'adaptateur détendu se rétracte conjointement avec l'aiguille, amenant la pointe de l'aiguille à se rétracter et à venir en butée contre la base à l'intérieur. En tirant davantage le plongeur, le piston est amené en butée contre la structure de butée du cylindre, permettant au plongeur de se rompre à une partie fragile prévue, assurant ainsi de façon absolue une non-réutilisation et permettant d'éviter des blessures par piqûre d'aiguille.
